A: Because they’re over fed and under exercised. There’s no magic here. The pet food companies make their foods the tastiest they can make it. And then there’s the misconception that when a cat isn’t eating it’s somehow sick. That’s not always the case.

Q: My cat has the run of the house, isn’t that enough exercise?

A: No. Could you get all the exercise you need just walking around your house? An indoor cat needs planned exercise. The best exercise is object play - playing with your cat with toys. That’s the answer to exercise problems, obesity, and how to get a well-adjusted cat. If your cat doesn’t get enough exercise, it comes out in bad ways.

Q: If I get another cat, will they get more exercise?

A: If it’s a kitten. Kittens are the high-energy ones. If it’s another adult cat, you have to be very careful. Bringing another adult cat into the house has very few positives for the established cat. What you need to do when you bring home another cat is buy a bunch of new resources - new toys, new food, new beds, new treats. So the association for your old cat is that this new cat comes in with a bounty, a dowry.

Q: What are some games I can play with my cat to get him moving?

A: Cats are predators, and the way to get them to play is to let them use their hunting talents. Buy toys and then use them to mimic the actions of the animals a cat would normally hunt - a mouse, bird, lizard, rabbit or bug. Take a laser pointer and skitter it across the floor like a bug. Get a wand toy that looks like a bird and pretend to land and take off. But don’t just flap it around. No bird acts like that. Try to think about what a bird really does and then reenact that with the toy. It’s all pretend play, but try to make it as real as possible for your cat.
